If you have a Circuit Fuse Tap (https://www.viofo.com/accessories/84-4pcs-circuit-fuse-tap-atc-ats-micro2-mini-adapter-holder.html ), just plug the yellow cable into the ACC fuse. I have it connected to "S-contact" - it is without power when the ignition key is removed. Connect the red wire to a fixed 12V and black to ground.Hi All just trying to install a hardware kit for my new A129 Duo into my BMW struggling to find a connection for the ACC cable due to this Cambus system!
Anyone had similar problems?
Any help suggestions would be appreciated
All sorted now works fine!took it to someone who new what he was talking about!The first so called Auto Electrion put both power cables together in the light cluster above the screen! Joke.
